do they have the detent on them or what cause i have seen different kits on the internet. Some cover up the stock detent holes but u have to drill some new holes for the detent on the other side of the gun

when milling an Imagine for eyes, you aren't doing anything with the stock detent. You only need the covers...and the 4-40 screws that hold them to the marker (in holes you drill and tap yourself). The cover on the left side may need to be modified to go around the stock detent but you leave the detent alone and work around it.
